- On these published prices SimpleVerifier costs less at every volume Kickbox's page prices (1,000, 10,000, 50,000, 100,000 a month).
- SimpleVerifier one-time packs ($9 for 2,500 emails or $19 for 10,000 emails) never expire but cover email verification only, without the API, finder or phone lookups. Pro includes them.
- Pro has no monthly cap, but runs at up to 45 checks a minute per account, so 100,000 addresses take about 37 hours. Larger lists queue rather than fail.
- “Not published” means Kickbox’s page did not price that volume; we do not extrapolate. Run your own numbers in the cost calculator.

How Kickbox meters usage
In Kickbox’s own framing: per-email fees, bought as credit packs. What to watch: verification is billed per email, so cleaning a large list is a variable cost you cannot forecast from the plan price.
What it does well: Kickbox is worth keeping if you need their deliverability consulting and sending reputation tooling, which is genuinely strong and not something a verifier replaces.
For small volumes Kickbox can cost less than Pro: up to 2,500 addresses can be bought from Kickbox for under $29.99. If that covers your list and you verify it once, Kickbox may be the better buy.
How to work out what Kickbox will cost you
- 1
Count how many addresses you verify in a typical month, including re-checks of lists you already cleaned.
- 2
Find the smallest Kickbox tier whose allowance covers that number in the plans table, and compare it with buying a pay-as-you-go pack of that size, if Kickbox sells one.
- 3
Check whether unused Kickbox credits expire before you would use them, and whether the plan meters finding and verifying from the same pool.
- 4
Compare the result with SimpleVerifier: one-time packs at $9 for 2,500 emails or $19 for 10,000 emails, or Pro at $29.99 a month with no monthly cap and a throughput of 45 checks a minute per account.
